Renewable energy
can be generated
continuously
practically without
decay of source

5. WHAT IS ENERGY ?
Energy lights our cities, powers our vehicles, and
runs machinery in factories. It warms and cools our
homes, cooks our food, plays our music, and gives
us pictures on television.
Energy is defined as the ability or the capacity to
do work.

7. WHY TO CONSERVE IT ?
We have limited resources available on earth.
Our demands are continuously increasing day
by day.
It is possible that someday most of the non-
renewable resources will be exhausted and we
will have to switch over to alternate energy
8. We save our money when
we save energy.
We reduce pollution when
we save energy.
We save our energy when
we save energy.

10. WHAT WE CAN DO ?
RECYCLE - compositing waste materials into new
products to prevent waste of potentially useful materials.
Turn off all electronic devices that are not in use. Not
only turn them off but try to remember to unplug them.
You will be surprised how much you will save with this
simple step!
Replace old light bulbs with energy saving fluorescent
bulbs. They may cost more, but will save you much more
in the long run.
13. At Home
•We should not keep lights
unnecessarily switched on.
• Reduce the energy your
appliances consume by analyzing
star ratings.
• Improve your water heating
efficiency to reduce energy costs.
At Public
Places
• Switch of the fans and lights in
the places like bus terminal and
railway stations when not
necessary.
• Switch off the street lights.
• Big Hoardings, lightened up for
the whole evening and nights are
other wastage of power which
can be and should be avoided
14. HOW WILL IT HELP ?
Let’s Take an simple example :
• let us assume electricity is available for Rs.4.00 per unit , a
100 watt bulb is used for 8 hrs a day then:
•If we replace a 100 watt bulb with 22 watt CFL ,
• The annual saving would be…
• Power saved : 100W– W = 78W
15. Recycling Fun Facts
Recycling plastic saves twice as much energy as
burning it in an incinerator
Recycling of one aluminum can saves enough
energy to run a TV for 3 hours
Recycling of one glass container saves enough
energy to light a 100-watt bulb for 4 hours
Each ton of paper recycled can save 17 trees, 380
gallons of oil, three cubic yards of landfill space,
4,000 kilowatts of energy, 7,000 gallons of water
and 60 pounds of air pollution
16. ENERGY CONSERVATION
IN INDIA
About 70% of India's energy generation capacity is from fossil
fuels, with coal accounting for 40% of India's total energy
consumption followed by crude oil and natural gas at 24% and
6% respectively. India is largely dependent on fossil fuel
imports to meet its energy demands.
By 2030, India's dependence on energy imports is expected
to exceed 53% of the country's total energy consumption. In
2009-10, the country imported 159.26 million tonnes of crude
oil which amount to 80% of its domestic crude oil consumption
and 31% of the country's total imports are oil imports. The
growth of electricity generation in India has been hindered by
domestic coal shortages[ and as a consequence, India's coal
imports for electricity generation increased by 18% in 2010
